MONTGOMERY, Alabama -- A man found guilty of filing at least 27 fraudulent 2011 tax returns requesting some $91,304 in refunds was sentenced to 30 months in prison on Tuesday.

Corey Thompson pleaded guilty to one count of conspiracy to file false claims and to one count of aggravated identity theft in connection with his involvement in a sophisticated stolen identity refund fraud conspiracy in July 2012, the U.S. Attorney for the Middle District of Alabama released.

According to court documents from the first case, in January 2012, Thompson and his co-conspirators filed at least 27 fraudulent 2011 tax returns that requested a total of $91,304 in refunds.

Thompson and his co-conspirators obtained the means of identification from a prison guard and from an employee at a debt collection agency.

Court documents also state that in 2011 and 2012, Thompson worked as an independent contractor for a cable company.

As an independent contractor, Thompson installed cable and internet access. While installing cable and internet service at people’s houses, Thompson hijacked the internet service of customers for whom he had performed work. From his home, Thompson used his laptop and his specialized knowledge and equipment to essentially shut down the customer’s internet and then take over that customer’s internet.

Thompson would then file false tax returns using the hijacked internet which made it appear as if the false tax returns were being filed by the customer. Thompson directed the tax refunds to be placed on pre-paid debit cards. The pre-paid debit cards were intercepted by the United States Postal Service.

The case was investigated by Special Agents of the IRS - Criminal Investigation and Postal Inspectors of the United States Postal Service. Trial attorneys Jason H. Poole, Justin Gelfand and Michael Boteler of the Justice Department's Tax Division and Assistant United States Attorney Jared Morris prosecuted the case.
